The National Space Research and Development Agency (NASRDA) says the recent tremor in Kwoi, Kaduna State, was caused by what it called “passive sources”.

A statement from the agency signed by the head of the Media and Corporate Communications unit of the agency, Dr Felix Ale, yesterday said the nature of the source would soon be determined after the completion of yet another investigation into the incident. There were specific details.

He said reports had established that the incidents were recorded in Kwoi and surrounding villages of Nok, Sanbah and Chori in Jaba LGA on Sunday, 11th and Monday 12th September, 2016.

“The current finding was the outcome of a preliminary report by the team of experts immediately deployed to the affected communities from one of the activity centres of the space agency: The Centre for Geodesy and Geodynamics for on the spot assessment and to carry out a survey and investigation on the incident”, the statement said.

The team which was led by the Head of Seismology division of the space agency, Dr. Ofonime Akpan, established that the seismological station of NASRDA located at Kujama in Kaduna State accurately recorded the incident which made it easy for collation of data and early release of preliminary reports on the incident, according to the statement.

The reports revealed that the time of occurrence of these events and intensities of the locations as reported by inhabitants of the communities which included cracks on walls of buildings, falling ceiling fans and other items correspond with results of analyses carried out by the team of experts from NASRDA’s Centre for Geodesy and Geodynamics.

The agency appealed to residents of the various communities to remain calm as no stone would be left unturned to unravel the situation as more data was aggressively being collected from other seismological stations. The agency promised to make its detailed reports known to the public as soon as further investigations on the incident were completed.
